WILLIAM HATFIELD, OF ZANESVILLE, OHIO.

WATER-WHEEL.

To all whom t may concern;

Be it known that I, VILLIAM HATFIELD, of Zanesville, in the county ofMuskingum and State of Ohio, have invented a new and useful Improvementin Parkers Percussion and Reaction lVater-lllheel, which is described asfollows, reference being had to the annexed drawings of the same, makingpart of this specification.

The main feature of this improvement consists in the peculiar shape ofthe buckets of the wheels and the arrangement of a double scroll fordirecting the water uponV said buckets in such a manner both above andbelow the axis of the shaft as to produce the greatest effect with theleast quantity of water.

The wheels A, A, are arranged in pairs on a horizontal shaft B, lyingacross the boxing of the mill and covered by the wheel chamber C.Between each pair of wheels is arranged a double spiral scroll block Dfor directing the water on the buckets to the right and left as well asabove and below the shaft at the same time. Each Wheel is composed of around solid head fastened on the shaft near the end thereof, having acurved rim around the peripheries of said heads divided into equalspaces or sections each of which containing a bucket E of the requiredshape, which is that of a section of an oval, the convexity being on theoutside and the concavity on the inside. It very nearly resembles thebowl of a table spoon with the handle and part of the large end cut off.The wheel when made of wood is strengthened by bands of iron F, aroundthe peripheries or edges and across the ends of the buckets. Both wheelsare made alike and are fastened on the horizontal shaft in va verticalposition with their open sides toward the center or toward the scroll.

The double spiral scroll block D, bears some resemblance to two volutesbrought together and secured in that position. The drawing Figure 4illustrates fully the peculiar form of said double scroll. The box ing Gand side decks H- are also made in the usual manner.v The concave I inwhich the scroll is placed is made something after the shape of a ogee,the convex part over which the water passes to the buckets being raisedmuch higher than in any other wheels for the purpose of directing thewater with great force against thebuckets below the axis of the shaftand conducting the same around to the buckets above the axis. The scrollcommences to scroll at the small end in front on either side and thuscontinues to increase until it performs a complete revolution around theshaft for the purpose of directing the water as before described. Thecap I is made in the usual manner.

The gate' is raised by the attendant by means of a lever or othercontrivance. The water enters the chute and passes on either side of thedouble spiral scroll block to the buckets of the two wheels at the sametime, thus dividing the water and directing it to the buckets above andbelow its axis on the wheel at the same time.

The invention claimed and desired to be secured by Letters Patentconsists in- The peculiar' form of the buckets and the double spiralscroll placed between them for directing the water in the manner abovedescribed.
